Illusion [34]

Answer:

let's see what to do buddy....

Step-by-step explanation:

3( \frac{7}{5}x + 4) - 2( \frac{3}{2} -  \frac{5}{4}x) \\  \\  =  \frac{21}{5}x + 12  - 3 +  \frac{5}{2}x \\  \\  =  \frac{(21 \times 2) + (5 \times 5)}{10}  x + 9 =  \\  \\  \frac{42 + 25}{10} x + 9 =  \frac{67}{10}x + 9 = 6.7x + 9

(6+3)4 I don't understand what it means I really need some help​
Over [174]

Answer:

36

Step-by-step explanation:

Hullo :D

If you're having trouble understanding, you might not understand the Order of Operations.

P - Parenthesis. Solve what's inside the Parenthesis first

E - Exponents. Solve for Exponents second.

M - Multiply. Multiply numbers third. (left - to - right with division, too)

D - Divide. Divide fourth. It is interchangeable with multiplication, as well.

A - Addition. Add fifth.

S - Subtract sixth. It is interchangeable with Addition, as well.

With that in mind, all we need to do is identify these types in the equation:

(6+3)4

We see parenthesis. We will solve them first according to the Order of Operations:

6 + 3 = 9.

(9)4

We see multiplication. We solve them next according to the Order of Operations:

9 × 4 = 36.

Thus, the final answer is \boxed{36}.

Hope this helps!

What is the value of n 9 x 23 +3 x39 - 28 = n
Flura [38]
Ok :) we should do according to order of operations
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction    (PEMDAS) 'it will be helpful for to remember '
 
anyways ;
9×23=207
3×39=117 
 (we did those things because we should multiple before add )
so now we will add and subtract= 207+117-28 =296
 
I HOPE IT WILL MAKE SENSE !!!!!!!
